Hi Greg. I am guessing this is a security problem rather than a programming one. If patrons of your internet café have the security access to modify your system files, that's what you need to address. Just make sure your "important files" are set to be accessible only by administrators, then make sure the accounts your patrons are using have significantly less privileges.

Hi Mike,
First thanks for your answer but I really need to implement this code. I try to explain to you my problem.
I have 16 computers running Xp Home and no domain, I 'm using a Cybercafé program named "Cyberlux" who need the administrative rights to run, and all my computers have 20 games installed on it. I have modified a lot of registry keys to ameliore the settings security and I have hide all the disk and importants documents on it but some of my young users find the way to access to all the system file with this f****** dialog boxes.
The hack : They go on a Web page where you can upload an image for exemple with a "browse" button on it, the dialog box open, they just have to put the entire path of a file on the field "Name of the file" to acceed where they want (hidden files or not). They go to the folder of my cybercafé program and move or delete the security files.
I hope you understand my problem and can explain to me how to apply this code.
Thanks for your answers.

You can't use this code to replace the File Dialogs in other applications. You REALLY need to overhaul your networks security so that your users do not have permissions to do anything that they are not supposed to do.

Okay,
Thanks for your reply I try to found another way to block the access to my important system files. 
Best regards,
Greg.

Yeah, it's a matter of setting proper NTFS permissions on your folders.
|
|
|
|
|
It's not so easy, look at my answer to Mike Ellison, I explain exactly my problem.
Perhaps you know a registry key I can modify to completly disable this dialog box?
Thanks.
|
|
|
|
|
Yeah, I read that, and my answer does not change.
The base of the problem is that you're running an app that needs admin permissions. Either find another app, or learn how Windows security works. You can create an admin equivilent ID that has no permissions to various parts of the file system.
There is no way to disable those dialog boxes.

Hi there. Yes, just to add my voice to what Dave has already posted - he's right. You'll definitely need to handle this through NTFS file permissions.
Given the nature of your cafe though, have you considered running your 20 machines in a genuine Windows domain? It wouldn't cost much to set up a server, let it be your primary domain controller, and have the 20 clients authenticate against it. You could then manage the security for all from one location. Just something to think about.

Hi, that's right, I don't remenber that I can activate the security tab on xp home edition. Now it will be easy to manage my rights. And a 2003 server is too expansive for my society but it will be the best effectively.
Thanks to have spend time to answer at my stupid question, I apologize.
Best regards,
Greg.

I'm looking for links (if possible) to good looking application UI's written using Windows Forms. I am wanting to see how good a program UI built using Win Forms can look, but with free stuff only, of course. Thanks

hi
iam currently using vs.net 2005 to make a window form on c#
i notice the event dragdrop for the listview control and would like to know if it is possible to drag a row from a listview to another row in the same listview and triggering an event as i was hoping to use it the group the 2 rows together
|
|
|
|
|
Is this[^] the type of thing you're looking for?
For what it's worth, I found it by searching for "listview drag and drop" in Google.
|

This is what I have currently:
(1) My form
(2) My menu bar with all the clicks I want on it
(3) A text box docked at the bottom of the form
This is what I'd like to happen:
(1) On launch of the program -
(i) I'd like for the program to ask a question, such as "What is your name?"
(2) On the answer of that question based upon input from the text box
(i) The first question to disappear
(ii) A second question to replace the first question
But I don't know how to make the text box docked to the bottom of the form input the text into the application and make the application continue to accept the responses and keep replacing the original question with a new question, etc. Can anyone help me with this?

So you are trying to build a wizard type application.
Presumably you have the main form appear when you run the program. Some things you will need.
A list of questions
A list of expected responses/validation rules (eg ask name and get back numbers)
Somewhere to store these usually a database or an XML file
Some mechanism that tells you where you are in the list (index will do)
A container for responses, List<string> will do.
Flow
Form opens
Populate the question list
Set the current index to 0
-----------repeat here
display the text in a label for the question in list[0]
when the user clicks NEXT button validate the text in the textbox
store the response in the response List
increment the current index and repeat until all questions are responded to.
deal with the list of responses, store the info in your preferred device.
You then need to address the back operation as well (then the index is decreased clear all responses above the current one)

Hi Teknowizard,
I am going to take your "ui" description literally and assume you really want to display a single question at a time, and I'm going to assume that you intend for the question to be displayed in the main area of the form (i.e., independently of the textbox docked to the bottom). Please correct me if that interpretation is not right.
So you have some method of showing one-question-a-time (textbox ?).
Maybe you have a timer controlling how long the question is visible ... whatever.
Now the user is typing their answer in the textbox : you are going to monitor the user's actions in the TextBox and at some point change the question.
There are many ways to do this, and I'll give you a few hints about design choices you can make with your user input textbox :
1. Multiline property of TextBox : will it be single-line or multi-line
2. AcceptsReturn property of TextBox : what will happen when the user hits the Enter key ?
3. AcceptsTab property of TextBox : what if the use enters tab ?
4. WordWrap property of the TextBox : if multi-line do you want to allow wrapping ?
Once you have experimented with and familiarized yourself with these properties, you can move on to Events of the TextBox.
Note that you could, by setting KeyPreview property of the hosting Form to true, handle key down/up/press events at the Form level.
I suggest you examine the following Events :
1. KeyDown
2. KeyUp
3. KeyPress
And consider the issue of what if the user clicks outside the TextBox : do you wish to make the Focus be restrained so the only thing the user can do is type in the TextBox : examine Events :
1. Enter
2. Leave
If you wish the user to "signal" when they are done entering an answer by some keyboard activity, you are going to need to write a Key Event Handler : start writing one now, and mess around with it, get familiar with KeyCode and/or KeyData properties of the EventArgs passed to a Key Event.
If you wish the user to "signal" they are done by some other means, well, up to you.
A few hours now of experimenting will pay big dividends for you in the future.
best, Bill

Take the jar of baby food out of the cupboard
get a pan of water
remove lid from jar
fill the pan 1/2 full heat on stove with the jar in the water
get a spoon from cutlery draw
when baby food is warm remove from the pan
use spoon to scoop some out
feed yourself
It's a joke Bill, a joke, honest it's a joke.....

Hi Mycroft, I don't know why I'm laughing  , but fully agree : that's funny !
My philosophy is : "why help a man to scream, when you can show him how to damn himself for all eternity."
best, Bill
p.s. there I was patting myself on the head (the one on my shoulders, I mean) for having done what I thought was a helpful thing. I thought, to use your metaphor, that I was telling the OP : "here's what you need to explore in order for your 'wisdom teeth' to come in so you can 'graduate' from pabulum."

It's a slow afternoon here and I seem to recall a Lounge rant against rude responders where you were given a hard time. It struck me a hilarious to see you attempting to spoon feed this person.
If I have you mixed up then I apologise but the rant and some of the reactions (Chris's reply sticky) has modified my response pattern, I now have to wait for some idiot to post a programming question in the Lounge to vent my sarcasm on.

Hi MyCroft,
Yep, you got me mixed up with someone else; I was the author of a strongly worded post[^] on the Site forum stating I believed people were frequently using requests for help to "take a dump on" posters on the technical forums, and this was hurting CodeProject, and was (is) just nasty pieces of work with no redeeming value.
Chris came out with the new guidelines soon after my post : of course, however, I do not believe my post was the "cause" of acton by Chris : I think he was hearing from many people on this same issue.
Don't you remember when you were a "newbie" in some technical arena, and you really didn't want someone to write your code for you, but you did need some pointing to what was really important to focus on so that you developed your understanding, were enabled to solve many problems, rather than just get a "quick fix" for a specific case you were not making progress with ?
When people have kindly replied to me here with helpful pointers when I have been stuck, I've always experienced that as "helpful enabling," not "spoon-feeding."
As I said in my long post on the Site forum : I'd like to see CodeProject, my favorite site in the whole world , my faithful old friend, my galaxy of revered gurus and teachers, have the same dynamic, evolving, kind of "tsunami" of sharing and interaction around problem solving for programmers that I see over on StackOverflow.
imho we can contribute to that partially by getting our jollies at our own expense rather than using people we don't know many of whom may not be "native" English speakers.
Let us, my friend, disprove the theory of humour espoused in the play "Comedians" by Joe Orton where he has the protagonist say, at one point : "the essence of humour is somebody else gets hurt."
best, Bill

I have managed to make use of the DwmExtendFrameIntoClientArea in Vista/7 to extend the glass effect into a form. However I cannot get this to happen on a form which is set as an mdi container. The glass portion just doesn't draw any more - it appears white. Note I'm not talking about the children inside the mdi parent, but on the actual main form itself.
Does anyone have any suggestions on how to get this working?
